State of the art on the effect of material property on tubular joints static behavior

Xue Jinke，Zhao Xianzhong

( College of Civil Engineering，Tongji University，Shanghai 200092，China)

Abstract：The current design codes have a restriction on material property, which will greatly limit the application of high strength steel in tubular structure. The authors introduce the limitation of various codes, the effect of yield strength, yield ratio and constitutive model on tubular joints static behavior, and summarize the effect of each factor.

Keywords：tubular joint; bearing capacity; high strength steel; yield ratio; constitutive model
